OT: Fastener Question

Does such a fastener exist...

I want to snap a steel bar over these "pegs" but with a quick push-to-release feature.

Thanks! ...Jim Thompson

I think what you're looking for is akin to the mechanism on a socket wrench ratchet handle. I've seen similar mechanisms on bike trailer wheels (push a button, a trapped ball bearing is allowed to drop back into the shaft and the hub can then slide off).

Or this , although I suspect you don't need Mil-spec.

Your automobile is full of similar fasteners used to hold plastic side panels in place. See if any of these looks close:

Yep, that scheme would work, just need to find one not attached to a socket wrench ;-) ...Jim Thompson

Pegs would hang down from a shelf, and bar would be pushed up from below to snap over the pegs. ...Jim Thompson

I know about those, bought a packet recently to repair my loose trunk liner, but they're semi-permanent, to release means pushing out the center pin. ...Jim Thompson

McMaster-Carr isn't the cheapest but they have a great variety to choose from. Carr-Lane and Reid also make these types of devices, if I recall coirrectly. DE-STA-CO I think also makes them. Fastenall is another company that sells some of this type of device. If you had asked in RCM you may have had even more answers. Eric

I've seen similar gizmos that have a handle sticking out so you can just grab and pull to release.

These are my opinions. I hate spam.

How about linch pins (Lynch), you do need to provide a shoulder with hole for them.

Quick-release pins have already been mentioned. A local race-car or light-aircraft shop may stock a few of these.

There are also Cleco fasteners. These get used to hold together sheet metal parts that you're about to rivet together; the "nose" of the pin goes through a hole in both sheets and expands to hold them together. Picture of some in use:

The "classic" Clecos need a special pair of pliers to take on and off, but there is also a kind that works with a thumbscrew. One supplier:

You might also find these at a local welding or sheet-metal supply house.

Suggestion: For answers to future questions in a similar vein, obtain and read this book:

Smith was a race car engineer, so that's the main application area the book discusses, but the bits and pieces he discusses are handy in many areas. This book is an expanded version of some of the chapters in at least one of his earlier books, "Engineer to Win". Unfortunately it seems to have gone out of print and now commands a silly price, but if you can find it at a used bookstore or something, it's worth it.
